VEHICLE-SEAT LOCK.

SPECIFICATION forming part of Letters Patent No. 452,472, dated May 19,1891.

Application filed January 15, 1891. Serial No. 377,927. (No model.)

To all whom, it may concern:

Be it known that I, DANIEL GLOVER BEERs, a citizen of the United Statesof America, residing at Newtown, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inVehicle-Seat Locks, of which the following is a specification, referercebeing had therein to the accompanying drawings.

My invention relates to a device known as a vehicle-seat lock; and itconsists, essentially, of a new construction and novel arrangementof ahook provided with lugs, of a cam-lever having acontinuous connected rimwith a shoulder upon the inside and outside of said rim, and of pipe-boxbearings with post and brace-plate, all substantially as here inafterdescribed and set forth in the annexed drawings, in which Figure 1 is arepresentation of this invention and shows a front of the lock with theupper extension-brace partly cut away, with cam-lever turned to theleft. Fig. 2 is a side elevation of the lock and section of seat-riserand seat-rail in elevation. Fig. 3 is also a front view of the lock withupper extensionbrace cut away and the cam-lever turned to the right, andFig. at is a perspective View of the hook. Fig. 5 is a rear view of theplate F. Similar letters refer to similar parts throughout the severalviews.

In the annexed drawings, the letter A designates a section of theseat-riser; B, the seatrail of the wagon; G, the lock attached to theseat-riser, and D represents the hook; D, the hook projection; E, thecam-lever, and E the rim of said cam-lever; F, the pipe-box bearings,and F the under extension of said pipebox bearings; G, the post on theside of the said under extension F and around which moved by taking outthe two opposite screws and the hook D, and the cam-lever E may then beremoved or replaced, as the case may be. The hook D is provided withthree lugs, which are placed upon the side of the shank namely, (1, d,and (1 (Z being upon the top and side of the shank and upon the sameside With the projection D. d is upon the side of the shank below and ona line with d, with a short space between; (I? is upon the side of saidshank a little to one side and above d, but not in a line with d.

The rim E of the cam-lever is adapted to operate between the lugs (Z andd, and when turned to the right the periphery of said rim engages thelug d and carries the hook D vertically downward in the pipe-boxbearingsF, releasing the projection D from the seat-rail B. In turning saidlever to the right the shoulder 6 upon the inside periphery of the rim Eengages the upper lug d and turns said hook one-quarter of a revolutionand holds the projection D parallel with the seatrail B, so that theseat may be moved backward or forward upon the said rail withoutinterference from the projection D. Now by turning said cam-lever to theleft the shoulder 6 upon the outside of the rim engages the lug d andturns said hook D back again into position, so that the projection Dcomes under the rail at right angles with the seat-rail. At the sametime the inside periphery of the camrim engages the lug (1, raising saidhook, and by turning said lever to its full extent to the left firmlyand securely locks the seat to the rail.

The pipe-box bearings F are extended vertically on the under side F toprovide for the post G, around which the cam-lever G revolves, and toform the lngf for attachingscrew, and the upper side to form the brace Gand plate G to connect with said post, said brace and plate beingadapted to take the strain from said post and to hold said cam-lever inposition. f are lugs for attaching-screws.

Operation: The operation is extremely simple. The hook D requires noadjustment by the hand, as in other seat-locks. The parts beingprovided, arranged, and adjusted as shown and described, the seat issecurely fastened and locked to the seat-rail by a single movement inturning the cam lever to the left, as shown. By turning the cam-lever tothe right the seat is released and the bend of the hook is turned to oneside and ontof the wayof interference with the seat-rail.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, in a vehicle-seat'lock, is

1. A vehicle-seat-lock hook having a lug at its upper end upon one sideand upon the same side, a short distance below, another lug, both lugsbeing on the same side of the shank with the projection of said hook,and having also a third lug slightly above the lower lug, alreadydescribed, but not on the same side of the shank with the projection ofsaid hook, as and for the purposes substantially as described.

2. A vehicle-seat-loek cam-lever having a circular and connected rim,said rim having a shoulder upon its inside periphery and upon theoutside periphery, as set forth and described.

3. A vchicle-seat-lock hook having three lugs upon the side of itsshank, one at the top on one side, another a short distance below on thesame side with the bend or projection of said hook, and the third alittle above but not in a line with the second lug, said hook beingadapted to move up and down in pipebox bearings by means of a cam-leverhaving a circular and connected rim, said rim having a shoulder upon itsinner and outer edges and being adapted to operate between and againstsaid lugs, by means of which said hook may be moved up and down inpipe-box bearings and turned one-quarter of a revolution backward andforward, as and for the purposes substantially as set forth anddescribed.

4. The combination of said hook with said cam-lever, the pipe-boxbearings of the extension F and post G, the extension-brace G, and theplate G all as and for the purposes substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.

DANIEL GLOVER BEERS.
